Endometriosis is a chronic disorder affecting approximately 10% of women in whom endometrial tissue forms painful lesions outside the uterus. It has a major impact on their physical, mental and social well-being but has no known cure, and there is no nonsurgical means of diagnosis. We have used a proteomic approach to identify proteins with altered abundance in the eutopic endometrium of endometriosis patients in the midsecretory phase of the menstrual cycle. 2D-differential in gel electrophoresis (DIGE) and mass spectrometry identified 20 proteins that were present at different levels in endometriosis patients (p < 0.05), many of which have not previously been associated with endometriosis...
